Subject: Regenerating etchant??

In the files section are instructions for
making etchant from muratic acid and hydrogen peroxide.
Sounds like something interesting to try.
As I understand it, you stick in the board and the copper goes
into solution. You regenerate the solution by bubbling air
through it. Ok, so where does all that copper go when you regenerate???
Thanks, mike
